Abstract

(57) [Summary] [Purpose] The air-conditioning feeling is improved by making the wind speed hitting the occupants comfortable for the occupants. [Arrangement] The wind speed at the position of the person in the room is calculated based on the angles of the louvers 5 and 6 for controlling the wind direction of the blown air, the speed of the airflow flowing in the airflow passage in the main body 1, and the operation mode of the air conditioner. By controlling the angles of the louvers 5 and 6 and the rotation speed of the fan 4 based on the calculated wind speed, the wind speed hitting the occupant is set to a comfortable value for the occupant.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air conditioner having a louver that controls the wind direction of blown air.

[0002]

[Prior Art]

 FIG. 2 shows an example of a conventional wall-mounted air conditioner. In FIG. 2, when the air conditioner is operating, the indoor air sucked into the main body 1 from the suction grill 3 is passed through the filter 8 as shown by the solid arrow to remove dust and the like in the indoor air. After being cooled, it is cooled or heated by passing through the heat exchanger 2 and is urged by the fan 4, and then the wind direction is controlled by the vertical louver 5 and the horizontal louver 6 to be blown out into the room from the air outlet 7. It

The cooling / heating capacity of this air conditioner is controlled so that the room temperature becomes a constant temperature. Then, the wind speed of the blown air blown out from the air outlet 7 can be switched by operating the wind speed changeover switch to switch the rotation speed of the drive motor of the fan 4 to three stages of high, middle and low speed. Further, the wind direction of the blown air blown out from the air outlet 7 can be changed by manually operating the vertical louver 5 and the horizontal louver 6.

[0004]

[Problems to be solved by the device]

 The air-conditioning feeling of the occupants is greatly affected not only by the room temperature but also by the wind speed hitting the occupants. However, in the above conventional air conditioner, since the wind speed and the wind direction of the blown air blown out from the air outlet 7 are individually adjusted, the wind speed in the air-conditioned area, that is, the wind speed corresponding to the person in the room is present. There is a possibility that the air conditioning feeling may be impaired because the comfort of the person may not match.

[0005]

Means for Solving the Problems The present invention has been proposed to solve the above problems, and its gist is to provide an air conditioner equipped with a louver for controlling the wind direction of blown air. A sensor that detects the angle of the above louver, an airflow velocity sensor installed in the air flow passage inside the air conditioner body, and the air-conditioning area based on the detected values of these sensors and the operation mode of the air conditioner. An air conditioner is provided with a calculating means for calculating the wind speed at an arbitrary position and a wind speed controlling means for controlling the wind speed at the above position.

[0006]

[Action]

 Since the present invention has the above-mentioned configuration, the wind speed at any position in the air-conditioned area is calculated based on the louver angle, the airflow speed, and the operation mode of the air conditioner, and the wind speed at this position is controlled. ..

[0007]

【Example】

 A control block diagram of the air conditioner according to the present invention is shown in FIG. The horizontal louver angle sensor 11 for detecting the angle of the horizontal louver 6 and the vertical louver angle sensor 12 for detecting the angle of the vertical louver 5 and the air flow passage in the main body 1, that is, the air flow passage from the suction grill 3 to the air outlet 7. An air flow sensor 13 is provided to detect the velocity of the air flow inside. The airflow sensor 13 is preferably installed on the downstream side of the filter 8 or the downstream side of the fan 4. The angle of the horizontal louver 6 detected by these sensors 11, 12 and 13, the angle of the vertical louver 5 and the speed of the air flow, and the output of the operation mode changeover switch 10 are input to the wind speed calculation means 14, where the detected values are obtained. Based on this, the wind speed at an arbitrary position in the air-conditioned area, for example, the position of the person in the room is calculated.

The result of this calculation is input to the wind speed control means 15, and here the angle of each horizontal louver 6 and vertical louver 5 is set so that the wind speed hitting the occupant becomes a wind speed that satisfies the comfort of the occupant. The rotational speeds of the horizontal louvers 6 are determined, and the results of these determinations are output to the motor 16 for driving the horizontal louvers 6, the motor 17 for driving the vertical louvers 5, and the motor 18 for driving the fans 4. Thus, the horizontal louvers 6 and the vertical louvers 5 and the fan 4 are driven by these motors 16, 17 and 18 and set to the values determined by the wind speed control means 15, so that the occupants of the room can feel the comfort. The blowing air at a constant wind speed hits, improving the feeling of air conditioning for people in the room. Other configurations and operations are similar to those of the conventional one shown in FIG.

Therefore, the wind speed at any position in the air-conditioned region is calculated based on the angles of the louvers 5 and 6, the velocity of the air flow in the air flow path in the main body 1, and the operation mode of the air conditioner. Even in the cooling operation and the heating operation, it is possible to accurately calculate where and how much wind speed is blowing in the air-conditioned area regardless of the clogging amount of the filter 8. The wind speed at a position distant from can be determined on the main body 1 side, and accordingly, it is not necessary to install a wind speed sensor in the remote control or the like. Since the wind speed at any position in the air-conditioned area can be controlled by the wind speed control means 15, the wind speed hitting the occupant can be set to a value that satisfies the comfort of the occupant.

[0010]

[Effect of the device]

 In the present invention, the wind speed at any position in the air-conditioned area is calculated based on the angle of the louver, the air velocity in the air flow passage in the main body, and the operation mode of the air conditioner. It is possible to accurately calculate the wind speed at any position in a remote air-conditioned area. Further, since the wind speed at any position can be controlled by the wind speed control means, it is possible to satisfy the occupant's comfort and improve the air conditioning feeling.
